The article analyzes the main characteristics of the state and metabolic activity of the biomass of soil microorganisms in the ecosystems of the near-lake salt meadows and dry steppes of the Western Baikal region. It is shown that during the transition from semi-hydromorphic soils (lake salonchak) to automorphic soils (chestnut soils of dry steppes), the levels of moisture and salinity decrease. Changes in soil properties lead to a significant transformation of the soil microbiocenosis. The study demonstrated that such soil-microbiological indicators as the carbon content in the biomass of soil microorganisms, basal respiration and specific metabolic activity, estimated by the value of the metabolic coefficient, can be successfully used in the practice of environmental monitoring of the near lake areas of the Tazheran steppe.
